Singapore signs Artemis Accords; Artemis I is 'Go' for Wet Dress Rehearsal

Singapore demonstrated its commitment to the peaceful and responsible exploration of space by signing the Artemis Accords, which set forth the guiding principles for cooperation among nations participating in NASA's Artemis program. Minister for Trade and Industry Gan Kim Yong signed the document during a ceremony March 28, 2022, in Washington.

Singapore is the 18th country to sign the Artemis Accords, more than doubling the original number of nations that signed in October 2020.

"I am excited that Singapore signed the Artemis Accords," said NASA Administrator Bill Nelson. "It's amazing how much worldwide commitment for this effort has grown over the past year and a half and I can't wait to see what the coming months bring as additional countries sign on to join our quest for peaceful exploration of space under Artemis."

Singapore is the third Asian country to sign the Artemis Accords, following Japan and the Republic of Korea. It is also the ninth country to sign under the Biden-Harris Administration.

NASA, in coordination with the U.S. Department of State, in 2020. The Artemis Accords reinforce and implement the 1967 Outer Space Treaty. They also reinforce the commitment by the United States and partner nations to the Registration Convention, the Rescue and Return Agreement, as well as best practices and norms of responsible behavior that NASA and its partners have supported, including the public release of scientific data.

Additional countries will sign the Artemis Accords in the months and years ahead, as NASA continues to work with its international partners to establish a safe, peaceful, and prosperous future in space. Working with both new and existing partners will add new energy and capabilities to ensure the entire world can benefit from our journey of exploration and discovery.

NASA 'Go' for Artemis I Wet Dress Rehearsal
In a pre-test review on March 28, NASA gave the "go" to proceed with the Artemis I wet dress rehearsal scheduled for April 1-3. The approximately two-day test will run the Artemis I launch team through operations to load propellant into the rocket's tanks, conduct a full launch countdown, demonstrate the ability to recycle the countdown clock, and also drain the tanks to give them an opportunity to practice the timelines and procedures they will use for launch.

During the rehearsal, controllers will countdown to T-1 minutes and 30 seconds and pause to demonstrate the ability to hold for up to 3 minutes, then resume until 33 seconds before when launch would occur, then pause the countdown. Then they will recycle back to ten minutes before launch and conduct a second terminal countdown to approximately 9.3 seconds before launch, then end the countdown.

Sometimes called a "scrub," launch controllers may decide not to proceed with launch if a technical or weather issue arises during or prior to the countdown. At the end of the test, the team will drain the propellant to demonstrate the procedures that would be used during a launch scrub. After draining the tanks, the team will review the test data before setting an official target launch date.

NASA's next moon rocket set for wet dress rehearsal ahead of launch
Washington DC (UPI) Mar 30, 2021
Having rolled the Space Launch System lunar rocket out to its launch pad and powered it up successfully, NASA engineers and technicians say they're just about ready for a prelaunch wet dress rehearsal this week. During the prelaunch test, which is scheduled to kick off Friday, the rocket and team will run through launch day procedures from fueling to just before startup, without actually launching the behemoth. "NASA's mega moon rocket is sitting at the pad, it's powered up and ready for ... read more
